PORTABLE QRUSHER.

citizen of the United States, residin at Milwaukee, in the county of Milwau ee and State of Wisconsin, have invented a certain new and useful Improvement in Portable Crushers, of which the following is a. specifcation.

This invention relates to improvements in the construction of portable Crushers and particularly to devices for permitting reduc-l tion of theoverall height of such Crushers to a minimum and for permitting ready feeding and discharge of the material to and from the crushers.

An object of the invention is to provide a portablecrusher which is simple in construction, efficient in operation and readily accessible for feeding. One of the more specific objects is to provide a portable crusher in which the crusher feed openings are accessible for feeding directly from the ground and without the. use of intermediary elevating devices. Another object is to provide portable crusher outfit in which the relativelyk heavy crushing devices are located as near tc the ground as possibleytliereby securing maximum stability. A. further object is to provide efficient and compact means for feeding or conveying the discharge from one of the Crushers to an elevating device without undesirably increasing the heiglht of the crusher inlet openin I Still a furt er object is to rovide a fee ing device which is simple 1`n its construction and readily accessible for inspection and re airs. A further'object is to rovide a feeding device which ma be rea ily adjusted to alter the rate o feeding. Still another object is to provide means for per.

mitting, either delivery of the entire coarse crusher discharge to a ne crusher, or for permitting shunting of the coarse crusher discharge to a wagon or other receptacle located at the side of the portable crusher outfit.

Some of the novel features shown and described but not claimed herein, form no part Speeicatlonot Letters Patent.

erence characters designate the same or similar parts in the various views.

Figure ,1 is a fragmentary, part sectional, side e1evation of a portable crusher outfit.

Fig. 2 is a fra entary, part sectional end view of a portal le crusher outfit, showing the means for shunting the coarse crusher discharge to a wagon, the section being of the resent invention and are claimed in -co-pen ing applications Serial Numbers 873,666 and 874,072.

A. clear conception of an embodiment of the invention. may be had by referring to the drawing accompanying and forming a part of this specification, in which like reff taken on the line II-II of Fig. l, looking in the direction of the arrows.,

Fig. 3 is a fragmentary, part sectional, enlarged side view of the jaw crusher and feeding device for delivering the discharge therefrom to the bucket elevator.

The portable crusher outfit comprises essentially a vehicle or truck l, a coarse breaker or jaw crusher 2, a bucket elevator 14, a fine crusher or rotary impact pulverizer 21, and a helical screw conveyer 22. The jaw crusher 2 is preferably mounted upon the truck 1 adjacent the extreme rear end thereof. The rotary impact pulverizer 21 is mounted upon the truck 1 near the mid portion thereofk and is adaptedto de liver its discharge to the screw conveyer which has an overlianging delivery end adapted for discharge into a wagon or other suitable receptacle. The vertical bucket elen vator 14 is mounted upon supporting beams 15 which are secured to the truck 1, and is located intermediate the jaw crusher 2 and the rotary impact pulverizer 21.

The jaw crusher 2, which in the present case is used as a coarse crusher, has an inlet openin 4.- which is located as near to the groun as possible, in order to rect feedin -of the material from t e ground to the crusher without the use of intermediary elevating devices. The movable or oscillato jaw 3 of the jaw crusher 2 is reciproca le by 'means of the rotary shaft5 hav-ing an `eccentric or cranke portion adapted to reciprocate the'pitman 6 and to ateinat'ely flexand straighten the tog g e 8. v

Below the discharge openin of the jaw crusher 2 is located a substantie y horizontal im-perforate reciprocable plate 9. The feed plate 9 is mounted upon resilient, substantially-parallel, oscillatory members or leaf springs 11, 12, which are xed to suitable ermit di-4 one end thereof which coacts with a projecting in 28 mounted in the lower extremity of the Jaw 3,- and having its 4opposite end slidably, adjustabl secured to the plate '9*b means of a suitable bracket and a set screw 2 The set screw 27 is operable in the bracket which is rigidl secured to the end of the plate 9. f Byre easing the set screw 27 and shifting the connection 10 longitudinally within the bracket and relative to the plate 9'l and then retightening the set screw 27,

the angularity of the leafs rings 11, 12,-

relative to a horizontal p ane, may be changed. By changing the angularity' of the -leaf springs 11, 12, the extent of movement of t e plate 9 and hencethe rate of feeding, may be readily varied.

The discharge end of the plate 9 is located directly over an apron 13 which is secured to the truck 1 and is adapted to deliver the material discharged thereagainst into the advancing buckets of the elevator 14. The elevator 14 comprises a series of bickets carried by a continuous chain which is movable by means of the usual sprockets to advance the buckets. The upper sprocket of the elevator 14 is mounted in adjustable bearings 17 which are4 supported by the upright beams 15 and permit ready adjustment of the tension of the elevator chain. The Iupper or discharge portion of the elevator 14 is provided with a discharge chute 18 having its delivery end -directed into a removab e spout 19, which in turn normally delivers into the feed hopper 2O of the rotary impact pulverizer 21. The lower extremity of the bucket elevator 14 is provided with manually operable devices 16 for permitting retraction of the lower extremity of the elevator 14 from the thread of the truck 1 during transportation.

The spout 19 may be readily removed by lifting the same vertically until its lower extremity is free from coaction with the feed hopper 20, and swinging the spout side- Wise to clear the hopper 20, after which the spout may be lowered to clear the lower end of the chute 18 and removed entirely. The shunting spout 23, s ee Fig. 2, may be suspended from the chute 18 upon removal of the spout 19 by means of supporting links 24, 25, which coact with suitable hooks secured to the chute 18, as shown in the figure. 1

During the normal operation of the crushers, the jaw crusher 2, bucketelevator 14, rotary impact pulverizer 21 and conveyer v 22, are given their proper operating movements b means of suitable mechamsm, not shown. he material to be reduced is fed into the inlet opening 4 of the jaw crusher 2; and after being partially reduced in this crusher, is discharged onto/ the feed plate 9. As the jaw 3 of the crusher 2 is reciprocated for crushing, a reciprocating motion is-also imparted to the connection 10, which in turn reciprocates the feed plate 9. The resilient supporting leaf springs 11, 12, during therecipro'cation of the plate, cause the plate to simultaneousl move'both horizontally' and vertically, t e degree of each motion depending u on the angularty of the elements 11, 1 s the plate 9 is moved vertically, the particles of material deposited thereon by the jaw Icrusher 2 are given a quick upward and forward motion tending to cause the same to move toward the discharge end .'of the (plate 9. As the plate 9 is quickly retracte after the forward impulse has been given to the particles of material, the partlcles fall by gravity and assume new ositionsupon the plate 9, which are somew at in advance of their previous positions thereon. In this manner the material discharged upon the plate 9'by the crusher2 is gradually and uniformly fed toward the discharge end of-the plate, being eventual] delivered to the apron 13 from which it 1s discharged into the approaching buckets of the elevator 14. The elevator 14 raises the material and eventually delivers the same into the chute 18 from which it is delivered by gravity either directly through the spout 19 to the feed hopper 20 of the impact pulverizer 21, or tothe shunting spout 23.

If the portable outfit is arranged for fine crushing, the material is recipitated through the spout 19 into the eed hopper 20 from which it is gradually delivered into the rotary impact pulverizer 21, wherein it is reduced to a fine powder. The material upon being delivered from the rotary impact pulverizer 21 is precipitated into the lower end of the screw conveyer 22, from which it is elevated 'by means of this conveyer and eventually discharged as desired either into a receptacle or upon the ground.

If it is desired to shunt the jaw crusher discharge, the spout 19 is removed and the shunting out 23 is applied as shown in Fig. 2. ith this spout 23 inserted in the machine, the material delivered to the chute 18 by the bucket elevator 14 is shunted and delivered directly to the side of the machine. The end of the spout 23 is preferably arranged so that the material may be delivered into a w on 26, as shown, if desired.

It will be noted that the feed plate 9 and the resilient supporting elements 11,12, provide a simple and compact feedin arrangement for effectively and uniformly feeding vthe jaw crusher discharge to the bucket elevator 14. The rate of feeding may [be readil?1 varied by relative adjustment of the feed p ate 9 and connection'lO by manipulation of the set screw 27. As the elements 11, 12, are of substantially the same length and are arran d parallel to each other, it is evident that lportions of the plate 9 have uniform motion, this feature being of considerable importance in vproducing uniform feeding of the material along the entire length of the plate. The substantially horizontal arrangement of the plate 9 permits location of the jaw crusher 2, and especially the inlet opening 4 thereof, as near to the ground as ssible, thereby permittin both ready ceding of the crusher 2 an producing a machine of maximum stabilit The feature of permitting sli'unti of the jaw crusher discharge is of considera le importance in machines of this type when used for both agricultural and road making purposes, since it is then desirable to have coarse crushed stone for and to have the pu tural urposes.

It s iould be understood that it is not desired to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

It is claimed and desired to secure by Letters Patent,-

1. In combination, a vehicle, `a crusher mounted upon the rear end of said vehicle and having its inlet located relative to the tread of said vehicle at a height permitting manual feeding by a single handling of the material, said crusher having stationary parts adjacent the rear end of said vehicle and having movable parts remote from said end, an elevator located upon said vehicle on the side of said crusher ad'acent to said movable parts, a substantially orizontal reciprocalble feed plate located directly below and in close proximity to the discharge of verized stone for agriculpurposes of road making crusher mounted uponthe rear end of said j vehicle, said crusher having a stationary jaw adjacent the rear end of said vehicle and having a movable jaw remote from said end, an elevator mounted upon said vehicle adj acent to said movable crusher jaw, an imperforate reciprocable feed plate located directly below and in close proximityl to the discharge of said crusher for delivering to said elevator material discharged by said crusher, a plurality of vibratory supportin elements associated with said plate andl wit said vehicle and extending at an angle to said late, a direct connection between. said movable crusher jaw and said plate for imparting reciprocating motion to said late, and means accessible from the rear otpsaid vehicle for effecting adjustment of said connection to vary the relative angularity Ibetween said late and said element whereby the rate of eedin may be altered.
